| Outline of Final Research Achievements |
Influenza A and B viruses and their infected cells express an enzyme “sialidase”. We developed and commercialized a probe “BTP3-Neu5Ac” for fluorescence imaging of sialidase activity. We developed a novel technique for selective fluorescence cell imaging of drug-resistant virus-infected cells and for high-efficiency isolation of drug-resistant viruses, as application of BTP3-Neu5Ac. For the purpose of exhaustive identification of sialidase mutations conferring drug resistance, we tried viral sialidase expression in yeast but did not succeed. As an alternative way, we developed an easy and speedy method for detecting drug-resistant virus by use of BTP3-Neu5Ac. This method is expected to enable efficient detection of drug-resistant viruses and to contribute to progress of research on drug resistance mechanism.
